Abstract

A substrate includes a display area and a non-display area with touch electrodes disposed in the display area, touch lines disposed in the non-display area and connected to the touch electrodes, a first power supply line disposed in the non-display area and having a first power supply voltage applied thereto, and a second power supply line disposed in the non-display area and having a second power supply voltage applied thereto, the second power supply voltage being higher than the first power supply voltage. Any one of the touch lines overlaps at least one of the first power supply line and the second power supply line. The first power supply line overlaps the second power supply line.

       2. The display device of  claim 1 , further comprising:
 a second planarization film disposed on the fourth sub power supply line. 
 
     
     
       3. A display device comprising:
 a substrate; 
 a first active layer disposed on the substrate and including a channel region; 
 a first gate insulating film disposed on the first active layer; 
 a first gate electrode disposed on the first gate insulating film and overlapping the channel region of the first active layer; 
 a first interlayer insulating film disposed on the first gate electrode; 
 a capacitor electrode disposed on the first interlayer insulating film and overlapping the first gate electrode; 
 a second interlayer insulating film disposed on the capacitor electrode; 
 a first sub power supply line and a third sub power supply line disposed on the second interlayer insulating film; 
 a second sub power supply line disposed on the first sub power supply line; 
 a fourth sub power supply line disposed on the third sub power supply line; 
 a fifth sub power supply line disposed on the second sub power supply line; and 
 a first planarization film disposed between the third sub power supply line and the fourth sub power supply line, 
 wherein at least one of the first sub power supply line and the fifth sub power supply line overlaps at least one of the third sub power supply line and the fourth sub power supply line. 
 
     
     
       4. The display device of  claim 3 , further comprising:
 a second planarization film disposed on the fourth sub power supply line; and 
 a third planarization film disposed on the fifth sub power supply line. 
 
     
     
       5. The display device of  claim 4 , further comprising:
 an encapsulation layer disposed on the third planarization film and including a first encapsulation inorganic film, an encapsulation organic film, and a second encapsulation inorganic film; and 
 a dam for preventing overflow of the encapsulation organic film, 
 wherein the first sub power supply line, the second sub power supply line, and the fifth sub power supply line overlap the dam. 
 
     
     
       6. A display device comprising:
 a substrate including a display area and a non-display area; 
 touch electrodes disposed in the display area; 
 touch lines disposed in the non-display area and connected to the touch electrodes; 
 a first power supply line disposed in the non-display area and having a first power supply voltage applied thereto, the first power supply line including a first sub power supply line disposed on the substrate, a second sub power supply line disposed on the first sub power supply line, and a fifth sub power supply line disposed on the second sub power supply line; 
 a second power supply line disposed in the non-display area and having a second power supply voltage applied thereto, the second power supply voltage being higher than the first power supply voltage and wherein the second power supply line includes a third sub power supply line disposed on the substrate, and a fourth sub power supply line;
